Description
technical field [0001] The invention relates to optical fiber data transmission technology in the field of data communication and camera technology in the field of video monitoring, in particular to a high-definition digital video monitoring device and monitoring method based on an optical fiber network. Background technique [0002] With the continuous development of broadband services, the capacity of the existing MAN and access network is insufficient. For operators, the most fundamental and practical and effective way is to expand the capacity of the land network and access network of the city. [0003] Optical fiber network has very obvious advantages in this respect: [0004] ⑴ Large capacity: the working frequency of optical fiber is 8-9 orders of magnitude higher than the working frequency of current cables, so the developed capacity is large; [0005] (2) Small attenuation: The attenuation per kilometer of optical fiber is more than an order of magnitude lower tha...
